可再生能量离网系统 第9-8部分:集成系统 小于或等于350 W独立运行可再生能量产品的要求

[中文适用范围]： IEC TS 62257-9-8:2025 提供了离网可再生能源产品的质量、耐用性和广告真实性的基线要求，以保护这些产品的消费者。这些要求的评估基于 IEC TS 62257-9-5 所描述的测试。该文件可以单独使用或与其他涉及离网可再生能源产品组件的安全和耐用性的国际标准结合使用。本文件适用于以下特性的独立可再生能源产品：- 产品由光伏（PV）模块供电或机电发电装置（如发电机），或者设计用于使用电网电能为电池或其他储能设备充电以供离网使用。该要求也可能适合其他能源来源的产品质量评估，例如热电发电机。- 光伏模块或其他发电装置的最大功率评级小于等于350瓦。- 评价的系统包括所有出售或包含在套件中的负载（照明、电视、收音机、风扇等）以及负载适配器电缆，并将这些组件集成在一起。- 光伏模块的最大功率点电压和套件中其他任何组件的工作电压不超过35伏。对于符合适当安全标准的AC-to-DC转换器，以及包括开路电压大于35伏且满足IEC TS 62257-9-5评估之外的额外安全要求的光伏模块（或组合光伏模块）系统的例外情况。本文件包含有关安全的规定；然而，它并不旨在成为全面的安全标准。特别是，该文件不打算用作替代诸如用于独立可再生能源产品中的无线电和电视等设备的IEC 62368-1或IEC 60335系列这样的安全标准。此外，它也不打算取代IEC 62281或UN 38.3中对电池运输安全的要求，或者取代用于独立可再生能源产品之外环境中的光伏模块的安全要求（如IEC 61730-1和IEC 61730-2）。 [外文原描述]： IEC TS 62257-9-8:2025 provides baseline requirements for quality, durability and truth in advertising to protect consumers of off-grid renewable energy products. Evaluation of these requirements is based on tests described in IEC TS 62257-9-5. This document can be used alone or in conjunction with other international standards that address the safety and durability of components of off-grid renewable energy products.This document applies to stand-alone renewable energy products having the following characteristics:- The products are powered by photovoltaic (PV) modules or electromechanical power generating devices (such as dynamos), or are designed to use grid electricity to charge a battery or other energy-storage device for off-grid use. The requirements may also be appropriate as guidance for evaluating the quality of products with other power sources, such as thermoelectric generators.- The peak power rating of the PV module or other power generating device is less than or equal to 350 W.- The system evaluated includes all the loads (lighting, television, radio, fan, etc.) and load adapter cables that are sold or included as part of the kit or integrated into kit components.- The PV module maximum power point voltage and the working voltage of any other components in the kit do not exceed 35 V. Exceptions are made for AC-to-DC converters that meet appropriate safety standards, and systems that include PV modules (or combinations of PV modules) with open-circuit voltage greater than 35 V that meet additional safety requirements beyond those assessed in IEC TS 62257-9-5.This document includes provisions related to safety; however, it is not intended to be a comprehensive safety standard. In particular, this document is not intended to be used as an alternative to safety standards such as IEC 62368-1 or the IEC 60335 series for appliances such as radios and televisions that are included with stand-alone renewable energy products. Nor is it intended to replace the safety requirements of IEC 62281 or UN 38.3 for battery safety during transport, or safety requirements of IEC 61730-1 and IEC 61730-2 for PV modules intended for use outside the context of stand-alone renewable energy products.
